[0042] The implementation principle of the puncture-resistant halogenated butyl rubber plug in the embodiment of the application is as follows: the rubber plug body 1 is inserted into the inside of the medicine bottle through the rubber gasket 104, thereby constructing an initial sealing environment for the medicine bottle; when the syringe enters the inside of the rubber plug body 1 through the puncture hole 101, the needle head abuts against the inclined gasket 303; as the syringe continuously and constantly descends, the downward force is transmitted to the limiting plate 302, and the limiting plate 302 slides in the limiting groove 202; as the plurality of limiting plates 302 are slidably installed in the inside of the mounting plate 201, the plurality of limiting plates 302 are in the open state at this time, and the drainage hole 204 and the injection hole 103 are in the corresponding state, which ensures that the needle head of the syringe can enter the inside of the medicine bottle without any obstruction, so as to smoothly extract the drug liquid.

[0043] When the syringe is pulled out, the buffer spring 304 utilizes its elasticity to transmit force to the limiting block 301, and then drives the plurality of limiting plates 302 to return to the closed state, thereby avoiding the drug liquid from leaking out of the pores or contacting with air, causing the drug liquid to be reduced or deteriorated, and the sealing of the inside of the medicine bottle can be maintained for a long time, and the drug product is maintained in a relatively stable environment, which is beneficial to prolong the shelf life of the drug product; when the telescopic assembly 3 is adjusted in the limiting assembly 2, the mounting groove 102 can ensure that the telescopic assembly 3 can be smoothly adjusted.

[0044] The above-mentioned embodiments are only preferred embodiments of the application, and cannot be used to limit the scope of protection of the application; any non-essential changes and replacements made by those skilled in the art on the basis of the application all belong to the scope of protection of the application.
